What To Do With Waterlines Next To Exterior Walls?

Answer:

Use caulk or foam to seal any holes where the pipes penetrate walls, floors, ceilings, or framing. If pipes run through exterior wall cavities, insulate the wall cavity just as you would the other cavities if using blown cellulose, fiberglass, or spray foam, which will easily fill in the space behind the pipes.

Answer:

This means you need to caulk the gaps between the wall studs and the exterior sheathing and any penetrations or holes in the top and bottom wall plates must be completely sealed. You then install the water line so that the pipe will be in DIRECT CONTACT with the drywall. The water line will be between the drywall and the insulation.
